Belt Tensioning Tips – A Technical Tip from Gates

V-Belt Tension Ranges for Manual Tensioners

Always use a belt tension gauge that indicates static tension, such as the Gates Krikit® Tension Gauge, to determine proper tension from the Installation Chart. Tension ranges below are for drives requiring single belts. If multiple belts are needed for a drive, divide tension by number of belts to give per belt tension to be measured.

  • Position belt and set tension to the prescribed Installation Tension.
  • Run belt for five minutes.
  • If belt tension drops below Suggested Tension range, retighten belt to Installation Tension. This will allow the belt to seat-in and run at Suggested Tension after it has operated under normal driving conditions.

Micro-V Belt Tension Ranges for Manual Tensioners

Always use a belt tension gauge that indicates static tension, such as the Gates Krikit Tension Gauge, to determine proper tension from the Installation Chart. Many Micro-V belts are automatically tensioned by a spring-loaded automatic tensioner, which does not require tension to be set.

The tension ranges below are used for applications requiring manual tensioning.

  • For drives with manual take-up on locked-center drives, position the belt and set tension to the prescribed Installation Tension.
  • Run belt for five minutes.
  • If belt tension drops below Suggested Tension range, retighten belt to Installation Tension. This will allow the belt to seat-in and run at Suggested Tension after it has operated under normal driving conditions.
